hay guys what hp will we need to run this 1972 dart swinger in the 6.50/6.00 range in the 1/8mile..car will be ladder bar with coil oversand as light as possible.power plant will be 400 block the inches are in the air right now with some good aluminum heads and a roller cam..thanks mike

the lighter you are the less HP you will need, whats your goal for weight?

i dont know as far as weight goes i dont even know what it weights now. just picked it up sat. its a 72 dart swinger . would be nice 3000 or under.. we are going to try for some fiber glass parts along the way with 2 race seats and a cage ,back will be ladder bars with stock frame rails, thanks mike

Do you want to go 6.50 or 6.00 in the 1/8 mile?

6.50 will take about 560-575 hp @ 3000lbs

As for 6.00, i'll let you know when i get there... But i'm guessing over 700hp at 3000lbs
Be forewarned, anything quicker than 6.40 in the 1/8 will require certified,caged car, NHRA license, etc...

ck the wallace racing calculator. think you will need around 750 hp.

this 69 dart is 3200 lbs with 500ci indy 440-1 heads. makes right at 750 hp. all steel but the hood with full cage, sfi to 8.50. 4-link car, 29.5x10.5W. it runs 6.20s @ 111 mph in the 1/8. it should go 6.0s with a little more tuning on it.
my son and i drive it for a friend of ours. he can't pass the competition lic.

I put a measley 495 hp and tq at the tires w/my 72 dart and 470 stroker and have been 6.22`s at 109+ and that`s at 3150 lbs ready to race. Heard loose verts give inaccurate numbers though so who knows.

my junk does 6.0's almost everytime at 112mph. it weighs 2950 with my fat ass in the chair & we're guessing it's about 720-730 hp with the undersized carb on it. rear gears are 4.8's with 32x14 slicks & a 5500 verter. common 60's are 1.38 & we pull the shifter at 7k.

...Only pic I have handy, my tube chassis street car. It's been 5.99/115/1.33 with a serious pump gas motor (10.28 comp). Did those number's with race gas. Weight is about 2625 with me, 2700 with street trim. Been on the street for ~ 6 yrs. Guessed 695-725 hp @ motor, don't know. 499ci, program caps, Indy-1 350cfm, ported intake,1050 carb,old Herb Mcandless/Ken Lasari roller,glide,4.56, & can set in traffic all day, serious!
...Note: the red hoses go to my small heater inside the car.

ok guys this is what i was thinking on the start of the build let me know what you would do or change to make this combo work.

car is 1972 dart
plan is to put fiber glass on the hood deck maybe fenders,keep stock glass, gonna keep stock frame rails and ladder bar the car,open wheel tubs up to fit as large a tire as possible,8 gal cell,cage.

motor 400 stroked 451/493 not sure yet
alum. rods as long as possible,short piston as light as possible
inter. bal. ass. crank will be forged
heads we're in the air first big block project but thought about the pro comps/ez/1s
cam will be a roller with the roller rockers
single plane intake with 4500 top if possible

727 worked over with a brake init 8' verta with some 4.56 gears...
add in what you think on this como please, my first big block and looking points from you fast guys....i like the build above

I think your list looks good. I would use -1's and a 274-280 @ .050 cam my

...It seems the Eddy heads are hard to beat for the $. I haven't used any myself, but i have a friend that has. His car is as light as mine, maybe lighter. He's motor is built healthier than mine (track only). He's down deeper in the 5's, last i remember 5.70's. He's was running a Toilet on Alky too, (more torq, more consistent) he was S/P Champ 3 out of 4yrs, ...deadly! "The Man". I think he was using the RPM head, the Vic's weren't out yet at that time.

my challenger runs 6.50s @ 3000lbs and I will be lucky to make 500hp. stock stroke 360 with good heads and a street roller.

I have been 6.02 in the 1/8
493, 12.8:1, indy cam R2 I think, 440-1 heads, indy intake, 1050, 8in PTC, 4:30 gear dana on 325 drag radials. best 60' of 1.29. 3380 Race weight. Drive it on the street a good bit. Horespower??? I have no idea.

thanks guys i didnt know the vic. where cap. of doing that so ill look into them as well.. that might save a few $ to use somewhere else....

hay Ron hows it going was hopeing you jump in i talk to you i think last year at the farmington mopar show we where on our way out the gate and stopped by to talk me and a few buddies....that thing you got really goes....

thanks guys and keep it coming in the combo....

does anybody have any idea of how much this 72 dart weight with all steel. i know i gotta get it out to weight it just kicks ...thanks mike

Indy has the 470 stroker kit for $1495! Or call bob George he has quite a few shortblocks ready to go! He is also an Indy dealer if you want a kit.

I have run 6.38 at 107mph with my 64B body at 3080 with driver. I used a .055 over 440, a 620-MP cam, a set of E-heads shaved .060 and a set of Rross 14cc domes at 0 deck, and 950-HP on a victor intake. On leaf springs. It dont take mutch.
